BAIL-ANCHOR.

Quebec and Dominion of Canada', have' invented certain new and useful Improvements in Rail-Anchors, of which the following is a full, clear, and exact description.

This invention relates to improvements in rail anchors, and the object of the invention" is to provide an inexpensive, durable and eflicient anchor having resilient means for securing it to a rail, whereby the anchor .will not become loosened by vibration.

A furtherobject is to provide an, anchor which is neither right-handed nor lefthanded, but may be applied against either of two adjacent ties and either inside or outside a rail.

The device consists briefly of a body member of substantially U-shape notched toward the extremities of its arms for the reception of the edge of a rail'base and adapted to receive between its arms below the rail base a spring hook engaging the opposite edge of the rail base, and a wedge holding the hook and body in rail engaging posi* tion. In the drawings which illustrate the invention;-. v

Fig. 2 is anend elevation of the device. Figs. 3 and 4:are views similar to Fig. 1 illustrating slight modifications. 1 Fig.5 is an end elevation of the device shown in Fig. 4.

I the upper surface of the rail base above it,

the inclination of'the Web 19 being pref erably about double the inclinationof the v The hook 16 comprises a flat strip of re silient material turned up at one end 21 to engage the opposite edge of a. rail base from the body and having a fiat'central portion 22 underlying the rail base and extending between the arms of the body. Beyond the prefflat portion,jthe strip is bent back under itself, as at 23, and terminates ina flat portion 2 1 lying on theweb 19 of the body and having its extremity abutting against the flat central portion 22. The portion 23 constitutes a very stiff C spring. c

The Wedge 17 is tapered to fit snugly between the rail base and the hook and to have full surface engagement with both when the hook is bearing against the web of the body 15. This wedge is of such length that its head 25 will project slightly beyond the body when it is fully driven home. As clearlyseen in Fig. 2, the width of the 'wedge is substantially equal to the width of the hook and both' substantially fill the space between the body arms so that no unnecessary play is allowed.

In the form shown n Fig. 3, the curved 4 or spring portion. 23 of the hook is slightly stantially horizontal or plain lower surface] 12 and an upper "surface 13 sloping upwardly from the edges toward the centrally dis osed web 14.

he anchor comprises a =body"1'5, and a retaining hook 16, and if desired a wedge 17. The body is preferably formed of a flat strip of metal bent' into U-form andhaving a pair ofsimilar parallel arms 18 connectedv by a Web 19. Each arm is provided withfa notch 20 locatedin' anedge thereof and toward the free end of the arm and designed for the reception of the edge of'th'e rail larger in diameter and the hook bears di-' rectly against the rail base, the wedge 17 being omitted.

In Figs. 4 and 5, the hook 116 comprises .a, flat central portion 122- having an upturned end -121and at the sides a pair of downturned triangular flanges 126 adapted to bear at their lower'edges on the web of the body. The body and wedge are exactly identical with these parts as described in connection with Figs. 1 and 2. u

The operation of the device is extremely simple. In the forms shown in Figs. 1, 2, t

. and v5, the body is driven onto one edge of a rail base, th e hook inserted through the body and its tip engaged with the opposite edge of the rail base.

the hook to such an extent that the hoo slips downwardly on the inclined web of the body and draws its tip very tightly against the edge of the rail base. This downward slip of the hook is obviously accompanied by adrawing of the body toward the center of the rail and, at the same time, the body is drawn downwardly by rea- The wedge beingheld'by the resilient hook cannot be worked loose by vibration. The form of device. shown in Fig. 3 is applied in a slightly different manner. The body is driven onto the edge of the rail base, as with the other forms, and the hook insertedas before. Pressure is then applied to the hook, preferably at about the point and in about the direction indicated by the base and arrow to compress'the spring portion 23 andmove the hook through the body until its tip 21 slips up over the edge of the rail base. The expansioir of the hook between the divergent surfaces of the rail base and body web urges the hook to movement in a retreating direction, so that its tip is drawn tightly against one edge of the rail it operates to draw the body against the other edge of the rail base.

The advantages" of this device are chiefly the resilient holding meanswhich make it.

proof against loosening by vibration combined with its simplicity, inexpensiveness and eiiiciency' The bite on the rail obtained by making the body a driving fit is very'greatfrom the outset and when pressed.

against a tieby rail movement, any oscillatlng tendency or cant serves only to increase the grip. The body projects cornerwiseinto drain readily and tained by driving the wedge between the hok member and the body web, but such an arrangement of the parts would render assembly extremely awkward, if not impossible. While the form of hook shown in Fig. 4' has been illustrated only in on-" junction with a key, it will be obvious that the body and hook may be assembled on a v rail without the key, as indicated in Fig. 3,

the body being flexed during driving and its resiliency serving to hold the turned-uptip against the rail edge.
